Abstract: When a network is requiring access barring, a mobile device determines whether a reference value broadcasted to the mobile device indicates a value determining that an access is denied regardless of a numerical value generated by the mobile device, or indicates a value having a possibility that an access of a certain mobile device is denied while an access of another mobile device is allowed. In the latter case, the mobile device determines appropriateness of an access by performing predetermined processing using the reference value as a value to be checked for a relationship with a numerical value generated by the mobile device when the mobile device does not have a special type access class, and uses a value enabling allowance of an access without performing the predetermined processing as a value for determining appropriateness of an access when the mobile device has the special type access class.
